Ran myself up a fever trying to select TLRs but they always seemed to be priced outta range, and settled instead onto an RB67 instead. (more value for money, i think). Although, of course there are the weight and other considerations. And a kilometre and a half walk with the RB was enough to run up a good sweat! :P
Inexpensive intro to medium format, aka the failure of the Pocket Kodak.
I have a few similar pocket folders, but you said "didn't come out" I skimmed the thread and didn't see anyone asking what that means, was it all black or all clear? If it was all black, you probably have leaky bellows and I would try wrapping it in duvateyn cloth (spelling?) first.
Secondly saw you mention the RB67, but the newer RZ67 pro II (NON "D" version) with Pro II backs don't have any seals to worry about and the whole system can be gotten fairly cheap.
Anyway just suggesting before you go crazy mentioning what you got or showing pictures of the film so we have a better idea of the issues. Did the edges still have markings? Etc.
Just my thoughts.
